Method: NMatrix#gesvd

Defined in:
lib/nmatrix/cruby/math.rb

#gesvd(workspace_size = 1) ⇒ Object

call-seq:

gesvd -> [u, sigma, v_transpose]
gesvd -> [u, sigma, v_conjugate_transpose] # complex

Compute the singular value decomposition of a matrix using LAPACK’s GESVD function.

Optionally accepts a workspace_size parameter, which will be honored only if it is larger than what LAPACK requires.
